Allow presigning to hoist more values into the URI

[aajtodd]

Describe the feature

There are currently some operations where the SDK could be hoisting more values that are bound to headers into query parameters when presigning. This would make the URI more usable without having users have to carry around both the URI and the headers that need to be sent.

Use Case

#1139

Proposed Solution

Possibly a new configuration option on presigning config. The issues is it's not clear when it's ok to hoist and when it's not. As an example polly pretty much requires hoisting whereas other operations do not. This really needs to be modeled...
